Add travis support

[chrisharper]

I've made some additions and alterations in order for authlogic to be ran on TravisCI ( http://travis-ci.org/ ).

All that is required is a new service hook being created ( http://about.travis-ci.org/docs/user/getting-started/ ) for the project.

You can also change the ruby selection and update notification preferences using the .travis.yml file ( http://about.travis-ci.org/docs/user/build-configuration/ )

If you have any questions let me know.

P.S I have created a picture of me in a monkey suit to persuade you : https://twitter.com/#!/_chrisharper/status/104482920701493248

Ha ha, my response is delayed, but that's hilarious. Let me look at it some more.

It looks like the Gemfile has changed since this pull request. Please see #368 for a new Travis config.
